In Figure 1, the handles l9 and were in posi- I tion for utilization ofthe jaws l3 and 14 having the opposed shear surfaces 15 and 55. The jawsl3 and 14 are adapted to be moved towardand away from each other bymerely moving the M handles toward and away from each other. Uponefiecting the movement of the handles 19 and 20 to a position whereinthe shoulders 35 and 3'! and 36 and 38 abut, further movement of thehandles 19 and 29 away from each other will cause the detent balls and21 to disengage from the depressions or seats and 31 of the jaws l! and18. The handles 19 and 20 can then be swung to the reversed positionsillustrated by dotted lines in Figure 1, wherein the device is inposition for the utilization of the long nose plier type jaws I! and 18.

Although only one embodiment of the present invention has been shown anddescribed herein, it is readily apparent that numerous modifications canbe made without departing from the spirit of the invention as defined bythe appended claim.

What I claim is:

-In pliers, a pair of crossed and pivoted jaw members, said jaw membershaving differing jaws on their opposite ends, the jaws on the same endsof the jaw members being arranged to cooperate when the jaw membersarepivoted relative to each other in directions to move the jaws at thesame ends of the jaw members together, apair of handles overlying theouter sides of 1. each other from the jaw members, said handles havinginner ends located at points intermediate the ends of said jaw members,a single pivot pin traversing intermediate points of said jaw membersand the said inner ends of the handles, said jaw members being rotatableon the pivot pin relative to the handles for reversing the jaw membersrelative to the handles, means acting between the jaw members limitingopening pivotal movement of the jaw members relative to each other, andabutment lugs projecting from the facing sides of said handles, saidabutment lugs being spaced along the handles from the said inner ends ofthe handles to abut portions of the outer edges of related jaws locatedintermediate the ends of the related jaws as the handles are movedtoward open positions and relative to the-jaw members so as to pivot thejaw members relative to each other in a direction to close the otherjaws, and spring biased detent meanshaving cooperating components on theouter sides of said jaws intermediate the ends of said jaws and on thefacing sides of the handles at points between the inner ends of thehandles and said abutment lugs for releasably connecting the handles tothe jaw members for pivoting the jaw members relative to each other inthe opposite direction so as to open said other jaws.
